[0002] With the development of minimally invasive intervention, minimally invasive interventional therapy for clinical heart and blood vessels has rapidly become an effective diagnostic method and treatment method. The femoral artery, brachial artery and radial artery of the human body are necessary ways for interventional diagnosis and treatment. When the femoral artery access and radial artery access are not applicable, the brachial artery access is also one of the safe and good choices clinically. After the brachial artery puncture catheter is removed, compression hemostasis is an important step to prevent complications of brachial artery puncture. For example, an invention patent application with publication number CN113069169 A discloses a brachial artery puncture point compression hemostat, which places a bone plate under the patient's arm so that the bone plate can support the patient's arm, and then the doctor inserts the plugs at both ends of the fixing ring into the two slots respectively, and fixes the plugs in the corresponding slots by fixing bolts. At this time, the fixing ring is fixed to the bone plate. When using the hemostat, the operation steps are complicated. Not only do the two ends of the fixing ring need to be accurately inserted into the slots, but the two bolts also need to be tightened to fix the fixing ring. In addition, during the compression hemostasis process, the bone plate cannot effectively limit the patient's hand, so that the patient's hand can bend, resulting in insufficient compression force of the compression device on the puncture point, and even the compression position moves.
